Application manual
When the setting Operation is set to Off, the behavior is set to Off and it is not possible
to override it. When a behavior of a function is Offthe function will not execute.
When IEC 61850 Mod of a function is set to Off or Blocked, the Start
LED on the LHMI will be set to flashing to indicate the abnormal
operation of the IED.
The IEC 61850-7-4 gives a detailed overview over all aspects of the test mode and
other states of mode and behavior.
• When the Beh of a component is set to Test, the component is not blocked and all
control commands with a test bit are accepted.
• When the Beh of a component is set to Test/blocked, all control commands with
a test bit are accepted. Outputs to the process via a non-IEC 61850 link data are
blocked by the LN. Only process-related outputs on LNs related to primary
equipment are blocked. If there is an XCBR, the outputs EXC_Open and
EXC_Close are blocked.
• When the Beh of a component is set to Blocked, all control commands with a test
bit are accepted. Outputs to the process via a non-IEC 61850 link data are blocked
by the LN. In addition, the components can be blocked when their Beh is
blocked. This can be done if the component has a block input. The block status of
a component is shown as the Blk output under the Test/Function status menu. If
the Blk output is not shown, the component cannot be blocked.

Setting guidelines

There are two possible ways to place the IED in the TestMode= On" state. If, the IED
is set to normal operation (TestMode = Off), but the functions are still shown being in
the test mode, the input signal INPUT on the TESTMODE function block might be
activated in the configuration.
Forcing of binary input and output signals is only possible when the IED is in IED test
mode.
Time synchronization TIMESYNCHGEN
Application
Use time synchronization to achieve a common time base for the IEDs in a protection
and control system. This makes it possible to compare events and disturbance data
between all IEDs in the system. If a global common source (i.e. GPS) is used in
different substations for the time synchronization, also comparisons and analysis
between recordings made at different locations can be easily performed and a more
accurate view of the actual sequence of events can be obtained.
